Her

The idea of Monica with big, bouncy breasts is impossible to get out of your head. If this weird power of yours listens to your desires even a little bit, you know what's about to happen when you pick Her.

Time snaps back into motion as you make your choice, and your thrusting hips spasm, unloading thick shot after thick shot of cum into your cute new partner. This big, muscular body of yours certainly isn't skimping out in the semen-production department. You idly wonder if your virility was similarly boosted before your attention is grabbed by Monica's body beginning to change.

As she laid before you, impaled on your cock, her fingers had been playing with her nipples, perched atop her cute handfuls of tit. Now her mounds were beginning to swell up bigger and bigger, quickly filling her palms and then pressing even further. Softballs, then cantaloupes, and she's still blossoming.

As her tits keep growing, you feel her entire body beginning to soften somewhat in your hands. Muscles toned from her weightlifting and fencing practice start to vanish under a layer of shallow fat. Her tits must make it harder for her to work out as much, you realize, as her hips start getting pudgier.

"Oh fuck, that's so good," Monica moans as you give a few more thrusts, your cock still half-erect even after cumming. Her now very sizable tits are still growing, and you watch with pleasure as she presses one big fat nipple up against her lips and starts nibbling and licking it, the mass of her growing breast slowly obscuring more and more of her face as she does so.

"Mmm, you like watching my tits bounce, don't you?" Monica says, apparently noticing how your eyes have stayed glued to her breasts. "That's good. I like it when people watch." They're absolutely porn-star huge now, but given how soft they look, there can be no question that they're 100% real. A vision of Monica walking into your shared stats class for the first time pops into your mind: she wore a tight blue t-shirt that did nothing at all to conceal the size of the two bowling ball-sized tits she'd squeezed into a bra that morning. Her rack was big enough that, standing, they filled her torso all the way down to her belly-button.

You finally notice Ava's hands stroking along your back. Has she been there the whole time? "Wow, stud, look at her now..." she whispers in your ear. "If I hadn't met your mother, I'd say they were the biggest tits I've ever seen in person in my life."

"You approve?"

"Definitely."

Carefully, you slide yourself out of Monica, who gives a little shimmy as the head of your cock exits. "Fuck, you're good at that," she says.

"Helps to have a beautiful partner," you say, grinning.

"Flatterer." She doesn't seem put off by it, though.
